7. Stargate SG-1 (1997-2007)

Roland Emmerich’s 1994 sci-fi epic starred Kurt Russell and James Spader but was a smidge disappointing. Three years later, Showtime unveiled this culty TV reboot, starting a year after the events of the film, when the US government learns that an ancient alien device called the Stargate can access a network of similar devices on a multitude of planets. SG-1 is the elite military special ops team brought in to explore the galaxy and search for alien technology via this mysterious portal. Lasting 214 episodes over 10 series, it overtook The X-Files as the longest-running sci-fi series in US TV history and spawned several of its own spin-offs.
